Answer:
The standard deviation of this sample is 7.438
Explanation:
We are given that Strength tests on four batches of concrete show them to fail at 81, 78, 86, and 95 ksi.
Data: 81, 78, 86, and 95
We are supposed to find standard deviation of this sample
Formula :[tex]\sqrt{\frac{(x-\bar{x})^2}{n-1}}[/tex]
n = 4
[tex]\bar x=\frac{81+78+86+95}{4}=85[/tex]
Substitute the values in the formula :
Standard deviation=[tex]\sqrt{\frac{(81-85)^2+(78-85)^2+(86-85)^2+(95-85)^2}{4-1}}[/tex]
Standard deviation=7.438
Hence The standard deviation of this sample is 7.438

A home health nurse who sees a client with diverticulitis is evaluating teaching about dietary modifications necessary to prevent future episodes. Which statement by the client indicates effective teaching
Answer:
"I should increase my intake of fresh fruits and vegetables during remission"
Explanation:
Diverticulitis is an inflammation or infection in one or more small pouches in the digestive tract. After the nurses' teachings a statement that would indicate this would be "I should increase my intake of fresh fruits and vegetables during remission". This is because, even though doctors say that patients with diverticulitis should avoid high fiber diets, when in remission eating lots of fresh fruits and vegetables is known to prevent acute diverticulitis.
The nurse understands that the client who is undergoing induction therapy for leukemia needs additional instruction when the client makes which statement
The question is incomplete as it lacks the group of choices or statements, however the generalized answer is provided on the basis of knowledge.

Which is the correct path of an electrical excitation from the pacemaker to a cardiomyocyte in the left ventricle (LV)?
Answer:
The question is lacking the options, below is the completely stated question and options:
This is the correct path of an electrical excitation from the pacemaker to a cardiocyte in the left ventricle (LV).
A. sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
B. atrioventricular (AV) node → sinoatrial (SA) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
C. sinoatrial (SA) node → atrioventricular (AV) bundle → atrioventricular (AV) node → Purkinje fibers → cardiocyte in LV
D. atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → sinoatrial (SA) node → cardiocyte in LV
E. sinoatrial (SA) node → atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → cardiocyte in LV
Answer:
The correct answer is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV (A.)
Explanation:
The electrical impulse conduction system of the heart refers to the pathways through which electrical signals pass, to cause excitation of specific paths of the heart, leading to depolarization, which in turn leads to contraction and relaxation of the heart. The correct excitation pathway is as follows:
1. Normal excitation originates in the sinoatrial (SA) node, from which depolarization spreads throughout the atria, causing impulses (excitation) to spread from the SA node to the atria. It is believed that this depolarization spreads to the atrial cells through adjacent myocardial cells and myofibrils.
2. Next, the depolarization from the atria reaches the atrioventricular (AV) node, causing excitation of the AV node. The AV node is located on the floor of the right ventricle, close to the interventricular septum. The excitation leaves this site by two pathways; the fast and slow pathways which vary based on the time of transmission of impulses to the next phase.
3. Next, from the AV node, the excitation is passed to the two branches of the bundle of His, which form a network of fibers known as purkinje fibers, from where excitation passes to the apical region of the left and right ventricles causing depolarization of the ventricular myocardium.
Attached to this answer is a picture to show what the pathway looks like.
The correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.
The heart is a cone-shaped hollow muscular organ that possesses the property of generating its own electrical impulses or excitations.
It is divided into four(4) chambers namely the right ventricle, left ventricle, right atrium and left atrium.
The correct path of an electrical excitation is from:
The pacemaker: This is also called the sinoatrial (SA) node. It generates the electrical excitations.Atrioventricular (AV) node: The electrical excitation initiated by SA node is then transmitted to AV node. This transmits the signal from atria to ventricles.Atrioventricular (AV) bundle: These are specialised fibres that originate from the AV node. They are the bundle that divides to form the right and left bundle branches.Subendothelial conducting network: This is also called the Purkinje fibres which is formed within the ventricular myocardium.Cardiomyocyte of the left ventricle: The cardiomyocytes are set of cells that generates contractile force in the heart. These are located at the left ventricle.Therefore, the correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.

What are some of the possible advantages and disadvantages of virtual autopsy’s?
Answer:
The only advantages of the virtual autopsy are the ability to replay and lack of exposure to pathogens. All of the disadvantages of being virtual vs in person are: lack of being hands-on; seeing, smelling, feeling and even hearing' sometimes even a "taste" in the air. Advantage of in person: Actual cohorts to get feed-back from and to. Advantages of virtual: you can't make a "natural" mistake virtually because it can be corrected. Some would say you can't make a mistake during autopsy, but this is false it can make or break a person's fatal diagnosis whether it be natural cause so many factors involved.
Some of the possible advantages of the virtual autopsy are as follows:
It creates digital and permanent records of the body, making it easier for pathologists and clinicians to communicate with each other.It can prove to be cheaper than conventional autopsies in some cases, with fewer resources needed and simpler to perform.It lowers the risk of contaminating pathologists and other medical personnel.What do you mean by Virtual Autopsy?A virtual autopsy may be defined as a noninvasive technique where non-intrusive human autopsies are performed by using a CT Scanner in order to obtain a detailed view of the body.
Some of the possible disadvantages of the virtual autopsy are as follows:
It is expensive and includes high equipment and technology costs.is new and is not fully accurate and thus may lead to false diagnoses and judgments.It needs skills and training to deduce from the autopsy results. Lack of experience is a disadvantage.Therefore, some of the possible advantages and disadvantages of the virtual autopsy are well described above.

According to the escience lab manual for lab 1, experiment 3, you need to prepare a 47 mL of a 24% soda/syrup prescription. To do this, you can use the 80% syrup solution and the 10% soda solution that you have in stock. How many mLs of soda solution do you need to create this final solution?
Answer:
33 mL
Explanation:
It is important to recognize that the total amount of pure syrup remains constant:
Total syrup in the stock solution = total syrup in dilute solution
Thus, we can use the dilution formula
V₁c₁ = V₂ c₂
Data:
V₁ = ?; c₁ = 80 %
V₂ = 47 mL; c₂ = 24 %
Calculations:
1. The volume of stock syrup
[tex]\begin{array}{rcl}V_{1}c_{1} & = & V_{2}c_{2}\\V_{1}\times80 \, \% & = & \text{47 mL}\times 24 \, \%\\80V_{1} & = & \text{1130 mL}\\V_{2}&=& \dfrac{\text{1130 mL}}{80}\\\\&=&\text{14 mL}\\\end{array}\\\text{You need $\textbf{14 mL}$ of stock syrup.}[/tex]
2. The volume of soda solution
Total volume of dilute solution = 47 mL
The volume of stock syrup = 14
Volume of soda solution = 33 mL
You need 33 mL of soda solution.

g what constitutes a healthy or normal bmi? what are some of the reasons it is useful to have a single number, such as a bmi, to describe a height/weight relationship? what are the drawbacks?
Answer:
BMI is the shortened form for Body Mass Index.
The Body Mass Index is a simple arithmetic for determining one's body fat using their height and weight.
The formula is given as
[tex]\frac{Weight (Kilograms)}{Height (Metres)}[/tex] or
[tex](\frac{Weight (Pounds)}{Height (Inches}) * 703[/tex]
If an adults BMI falls within the 18.5 to 24.9 range, it is considered healthy.
One of the benefits of using BMI as a health metric is that it is so easy to compute.
Its major disadvantage is that it only accounts for height and weight which can be altered by a variety of circumstances and as such in most cases are not the best indicators of whether or not, one if healthy.
For example, a higher muscle mass will mean more weight and as such, a higher BMI. Generally speaking, more muscle and less fat is healthy. So BMI, in this case, is useless as a metric of health status.
Other factors which alter the reading of BMI are: Gender, Frame Size, Age,
Pregnancy etc.
An individual who is very muscular, pregnant, or have a large frame, will most likely have a higher BMI calculation which may indicate that one is obese or overweight when they're not.
